Final answer:
When a workplace lacks close proximity to medical facilities, it should ensure that personnel are adequately trained in first aid and that first aid supplies are readily available.
Step-by-step explanation:
In the absence of an infirmary, clinic, or hospital in near proximity to the workplace that is used for the treatment of all injured employees, both adequate first aid training for personnel and the availability of adequate first aid supplies are required. Ensuring that employees are properly trained in first aid is crucial to provide immediate assistance in case of emergency. Additionally, maintaining a well-stocked supply of first aid materials ensures that the necessary tools are on hand to address a wide range of potential injuries until professional medical treatment can be received.
